A device for use in identifying or authenticating a subject positioned in an acquisition volume on the basis of at least one biometric characteristic of the subject, the device including in succession, in offset manner along a camera placement axis: a first camera; a second camera; and a third camera; the optical axes of the first and second cameras forming between them an angle strictly less than 10°, and the optical axis of the third camera intersecting the optical axes of the first and second cameras, the optical axes of the first and second cameras each forming an angle less than or equal to 5° relative to a normal axis perpendicular to the camera placement axis.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The device according to claim 1 , wherein the optical axes of the first and second cameras are substantially parallel to each other.
3. The device according to claim 2 , wherein the optical axes of the first and second cameras are both parallel to the normal axis.
4. The device according to claim 1 , further comprising, in addition to the first, second, and third cameras, an incorporated iris image taking system in communication with an iris recognition system, said iris recognition system being configured to recognize at least one iris of the eyes of the subject from at least one image of one or both of the irises of the eyes of the subject as taken by the iris image taking system.
5. The device according to claim 4 , wherein the iris image taking system is a system for taking an image of a portion of the texture of at least one iris.
6. The device according to claim 1 , wherein: the first camera is placed at a first height h 21 ; the second camera is placed at a second height h 22 higher than the first height h 21 ; and the third camera is placed at a third height h 23 higher than the second height h 22 .
7. The device according to claim 6 , wherein the optical axis of the third camera extends towards a positioning surface on which the subject is to be present in order to perform identification or authentication, and the optical axes of the first and second cameras are both parallel to the normal axis.
8. The device according to claim 6 , therein the optical axis of the third camera and at least one of the optical axes of the first and second cameras extend towards a positioning surface on which the subject is to be present in order to perform identification or authentication.
9. An automatic door fitted with the device according to claim 1 .
